[PATCH net-next v2] microchip: lan865x: add ndo_eth_ioctl handler to enable PHY ioctl support

[Parthiban Veerasooran]

Introduce support for standard MII ioctl operations in the LAN865x
Ethernet driver by implementing the .ndo_eth_ioctl callback. This allows
PHY-related ioctl commands to be handled via phy_do_ioctl_running() and
enables support for ethtool and other user-space tools that rely on ioctl
interface to perform PHY register access using commands like SIOCGMIIREG
and SIOCSMIIREG.

This feature enables improved diagnostics and PHY configuration
capabilities from userspace.

v2:
- Replaced custom lan865x_eth_ioctl() with direct use of
  phy_do_ioctl_running() to avoid code duplication.
- Updated commit message to reflect the new change.
